Charged Excitons in ZnSe-Based QWs

Abstract

We report on magneto-optical studies of ZnSe/(Zn,Mg)(S,Se) and ZnSe/(Zn,Be,Mg)Se quantum wells with n type and p type modulation doping. Negatively and positively charged excitons related to the heavy-hole exciton state are found and identified by their polarization properties. Exciton and trion parameters (radiative and nonradiative dampings, g factors) are determined.
